  • Publication number: 20160144392
    Abstract: An apparatus for organic layer deposition is provided that can improve precision of a gap between a substrate and a mask by correcting a position of a mask stage having a mask mounted thereon based on a substrate shape, and that can reduce a measurement error of a mask surface by pre-measuring a position of a mask and determining an initial position of the mask based on the measured position. The apparatus includes a shape measuring sensor, a substrate carrier, a deposition material discharge source, a mask including a plurality of pattern slits, a camera measuring an alignment error between the substrate and the mask, a distance measuring sensor measuring an alignment error between the substrate and the mask, and a mask stage controlling a position of the mask.
